The Roamer 200XTREME doubles the capacity of the 100XTREME while keeping the same arctic-grade performance. 200Ah of usable lithium power that charges from -30°C without a heater — built for serious overland expeditions, winter van life, and high-latitude use where temperature is not just a seasonal issue.
